Forged Socket fitting play a crucial role in industrial pipeline systems, and their quality and performance directly affect the safety and stable operation of the entire system. ASME B16.11 forged socket fitting stand out among many industries due to their strict standard specifications and become an ideal choice for pipeline connections.
Shanghai Zhucheng Pipe Fittings Manufacturing Co., Ltd. specializes in the production and sales of various types and materials of socket weld fittings. ASME B16.11 forged socket fitting we sell use advanced forging technology and are supplied strictly in accordance with production and material standards. The size range is from 1/8"to 4", with pressure ratings covering Class3000, Class6000, and Class9000 . The product complies with international standards such as ASME B16.11 and BS 3799. We are committed to providing customers with reliable product quality and stable delivery cycles to meet the strict requirements of various complex engineering projects.
The ASME B16.11 standard was developed by the American Society of Mechanical Engineers (ASME), which mainly regulates the manufacturing of forged socket fittings and threaded fittings. This standard provides detailed regulations on the pressure, temperature rating, size, tolerance, marking, and material requirements of pipe fittings.
The pressure rating classification is extremely detailed, and the pressure rating of socket weld fittings is divided into Class 3000, Class 6000, and Class 9000; Threaded fittings are Class 2000, Class 3000, and Class 6000. The common size range (NPS) spans from 1/8 inch to 4 inches, meeting the connection requirements of pipes with different diameters, ensuring that fittings can provide stable and safe connections for pipeline systems under various pressure environments.
EN 10241 Standard: This standard specifies the entire manufacturing process of industrial socket welding and threaded fittings, with clear requirements for5 material selection, manufacturing processes, final dimensional inspection, testing, and other aspects. It is widely used in the European market and regions that follow the European standard system, providing unified and strict specifications for the selection of pipe fittings for local industrial pipeline construction. In terms of materials, the chemical composition and mechanical properties of carbon steel, alloy steel and other materials are different from those of ASME B16.11 forged socket fitting; On the dimension annotation, although some specifications have similarities, there are also differences in details, such as stricter control of dimensional tolerances for certain special pipe fittings to meet the precision requirements of European industry.
BS 3799 Standard: BS 3799 is a standard developed in the UK for socket welding and threaded fittings of forged carbon steel and alloy steel. It is widely used in Commonwealth countries and some areas deeply influenced by British industry. This standard has clear specifications for the design, manufacturing, inspection, and other aspects of pipe fittings, covering the common size range from 1/8 inch to 4 inches. In terms of material requirements, BS 3799 has specific limitations on the carbon content of carbon steel and the alloy element content of alloy steel to ensure the mechanical properties of pipe fittings under different working conditions. In terms of pressure rating, the corresponding pressure rating to ASME B16.11 is specified, which facilitates selection reference under different standard systems. At the same time, BS 3799 has its own characteristics in details such as thread accuracy of pipe fittings and dimensional tolerances of socket parts, emphasizing the sealing and reliability of pipe fittings connections, and is suitable for medium and high pressure pipeline systems in multiple industrial fields such as petroleum, chemical, and power.
JIS B2316 Standard: This standard mainly applies to forged socket fittings, covering various product types such as elbows, tees, reducers, etc. Detailed explanations have been provided on the material characteristics, manufacturing process details, inspection procedures, and acceptance criteria of the pipe fittings. JIS B2316 is widely referenced in Asia and some other regions. In terms of material selection, it focuses more on common steel grades in Japan and has unique requirements for surface treatment and anti-corrosion processes of pipe fittings to adapt to the complex climate and industrial environment in Asia. For example, in some coastal areas, the requirements for the resistance of pipe fittings to seawater corrosion are more prominent.
ASME B16.11 offers a wide range of forged socket fittings, with sizes ranging from 1/8"to 4". Whether it is precision instruments and equipment or ordinary industrial production pipelines, suitable fitting sizes can be found, providing great convenience for the design and construction of pipeline systems.

Divided into 45 degree and 90 degree elbows. The 45 degree socket elbow is suitable for pipeline systems that require small angle turns, which can effectively reduce the resistance of fluid at the turning point and reduce energy loss; The 90 degree socket elbow is commonly used in the scenario of right angle turning, and its forging process gives it good structural strength, which can withstand high-pressure fluid impact and ensure stable operation at the turning point of the pipeline.
Equal diameter three-way with three identical port sizes, used to achieve fluid diversion or merging, ensuring uniform distribution of flow in each branch; The three principles of reducing diameter have a different port size, which can adapt to the connection and diversion needs of pipes with different diameters. Socket tees can also be divided into two types: equal diameter and reducing diameter. They are mainly used for four-way pipeline intersections. In complex pipeline networks, they can efficiently achieve fluid transmission in multiple directions. They are commonly used in circulating water systems in large industrial plants, material distribution systems in chemical plants, etc., providing key support for the flexibility of pipeline layout.
Including double socket tube clamps and single socket tube clamps. Double socket pipe clamps are used to connect two sections of pipes with the same diameter, achieving straight extension of the pipes. Their socket connection method makes installation simple and has good sealing performance; One end of the single socket pipe clamp is a socket, which can be welded to the pipeline, and the other end can be connected to other pipe fittings or equipment. It is commonly used for transitional connections at the interface between pipelines and equipment, and is widely used in the connection of steam and water pipelines and equipment in power plants.
Used to seal the end of a pipeline while ensuring stable internal pressure. The forging process ensures the strength and sealing of the pipe cap, making it easy to open or close the pipeline during maintenance and repair, ensuring the normal operation of the system.
One end is a socket welding connection, and the other end can be selected with threaded connection or other connection methods according to needs. It is suitable for transitions of different connection forms, as well as pipeline parts with limited space or frequent disassembly, such as pipeline connections in narrow spaces of ships. It can ensure a firm connection and facilitate later maintenance.
It can achieve pipeline branching at a specific 45 degree angle. Compared with ordinary tees, it can more accurately meet some special pipeline layout requirements. In the branch design of building water supply and drainage systems, pipelines can be flexibly arranged according to spatial structure to improve space utilization.
ASEM B16.11 forged socket fittings are formed by forging blanks from round steel or steel ingots, and then precision machined by lathes to ensure accurate dimensions and smooth surfaces, laying a solid foundation for the sealing and stability of pipeline connections.
